Abstract (en)

[origin: WO9741372A1] In a seal or bearing that uses the tapered-sleeves-with-spiral-groove technology, the capacity is increased, without increasing the space envelope, by folding the tapered surfaces. Double and triple folding is illustrated. The seal/bearing may be used in e.g. a rotary impeller pump, or as a big-end bearing.
